<FIGURE>Depth recovery by RGBD & Depth-only approaches.  (a) Depth map estimated from ground-truth RGB-image using MiDaS [1]}. (b) Depth channel of RGBD reconstruction directly from fMRI. (c) Depth recovery directly from fMRI, where both Encoder & Decoder are trained “Depth-only” – without using any RGB data for training. (d) Indirect depth recovery from reconstructed RGB-images using MiDaS. This approach fails to recover depth faithfully. (e) Depth reconstruction mean rank for (b)-(d) respectively by n-way rank identification experiments (lower is better, showing average over all 50 reconstructed depth maps and five subjects). \(95\%\)  Confidence Intervals by bootstrap shown on charts.
